WIND-ENGINE.

SPECIFICATION forming part of Letters Patent No. 258,650, dated May 30, 1882,

Application filed December 1, 1881.

To all whom it may concern Be it known that l, EPHRMM HOWLAND, of Pontiac, in the county of Oakland and State of Michigan, have invented an Improvement in kvind-Engines, of which the following is a speoication.

The nature of this invention relates to certain new and useful improvements in the construction ot' wind-engines; and the invention consists in the peculiar construction, arrangement, and various combinations of the parts, all as more fully hereinafter set forth.

.Figure l is a perspective view. Fig. 2 is a Fig. 3 is a sectional elevation.

In the accompanying drawings, which form a part of this specification, A represents a turn-table mounted upon a suitable frame, B. Upon this turn-table is erected the carrying-` frame C, between the standards or vertical side bars of which is pivotall y secured the frame D, eccentric to its longitudinal center, and which carries the operating parts of my device. Between the top girt, E, and girt F of this frame are pivotally secured the sails Gr, the lower journals of which project downward through such girt, and are provided with the links a, which project at right angles to said journals, for the purposes hereinafter described.

G is a guide-bar, the ends of which travel in suitable boxes, b, secured to the frame D; and said guide-bar is provided with outwardlyprojecting pins or studs c, which enter the eccentric loops a. Projecting from this guidebar G are two arms,H, the outer ends of which are connected by means of a yoke or strap, I, which embraces loosely the vertical sides of the frame D; and from the outer faces of these yokes project pins d, which enter slots e in the levers J, which are provided with the adjustable weights K, the lower ends of these levers being rigidly secured to the outer ends of a cross-rod, L, which is properly journaled in the sides of the frame D in such a manner that the operation of the two levers and their attachments upon each end of this rod shall be simultaneous. Thelower ends of the side bars of the frame D project downward, and are braced from the girt M by means of the braces N, which are provided with the counter-weights O; and from this girt M, at the' longitudinal (No model.)

center thereof, projects a bifurcated segmental yoke, P, which receives the head of the pumprod R, which is provided with the cross-head S, upon which are arranged frictional rollers which come in contact with the Lipper face of the scgmcn tal yoke P,whi1e the pump-rod projects downward through a proper barrel, T, rising from the turn-table A. While this form and the girt M is shown in my drawings, I do not desire to limit myself to this construction, as there are variousineans by which this connection could be made which would perform theI functions fully as well as the ones represented, while their cost would be materially less. The turn-table A is provided with the vane U, as in the ordinary construction ot' windmills.

follows: Supposing the frame D, with its various connections, to be standing inclined toward the'wind, which would of necessity cause the weighted lever J to stand at aproportionately greater angle from the vertical center than that assumed by the frame, and that the sails from this disposition of parts are closed, as represented in dotted lines in Fig. 3, the wind then coming from the direction shown by the arrow, striking against the sails, forces the frame over into the position shown in dotted outlines, Fig. 2, while the various other parts assume the positions shown in dotted outlines, same figure; and that as the leverJ in this movement is carried past the vertical plane it must by force of gravity fall into the position shown in Fig. 2, and must necessarily, in its movement, owing to its being shorter than the frame, increase its velocity as it passes such center, overtake and pass the frame D in itsy lnovement from the wind, and exert a force by means ofthe pins d and slots in the levers to cause the guide-bar G to slide in its guides b, necessarily compelling the pins c, in their engagement with the eccentric links a, to turn the sails G out of the wind, as shown in Fig. l; and in this movement of the parts, while the top of the frame D is thrown to the rear, the foot thereof, below the pivotal point of the frame, must necessarily be thrown for@ ward, and as a natural result an upward stroke of the pump-rod, by reason of its connection,

or manner ofconnection between the pump-rod In practice the operation of this device is as must be made. At this point, the sails having been turned so that the wind will have little or no effect against them, the weight of the pump-rod and the counterbalance-weights O upon the braces Nis and must be sulcient by gravitation to again elevate the frame to a position approaching that from which it started, and at a given time in the movement of the device the levers J, with the weights K, by passing over the vertical center of' the pivot, necessarily assume their original position, and in consequence ofthe connections hereinbet'ore named compel the sails to close, when the device is again ready to receive motion through the action of the wind.

Vlxat I claim as my invention is- 1. In a wind-engine, a counterbalanced frame supported on journals upon the turntable, and provided with a series of piroted wings adapted Vto be opened or closed by the downward or upward movement of the frame, substantially as described.

2. The pivoted and coun terbalanccd frame B, provided with a series of pivoted sails or wings, G, in combination with the pivoted weight-arm J and connections, substantially as described, between said weigllt'arm and the' sails, whereby the movement of the frame and the weightarm opens and closes the sails, as and for the purpose specitied.

3. In a wind-engine, substantially as described, the pivoted frame l), braeerods N, and adjustable counterweights O, as and for the purpose specified.

4. In combination with the pivoted and counter-balanced frame D, the pivoted sails G, provided with links a, tbe sliding bar G', provided with pins c, and the pivoted weight-arm J, substantially as described.

5. In combination with the pivoted and counter-balanced frame D, the pivoted sails G, and means, substantially as described, for turning said sails by the upward and downward movement of the frame, the bifurcated arm P, secured to the frame I), the rod R, and the side projections, S, on said rod, as and for the purpose specified.

6. In combination with the frame D, carrying the sails G, the sliding bar G', weightlever J, and connections, substantially as described, between the bar G and sails, as set forth.

7. The pivoted and counter-balanced frame D, carrying the sails G, in combination with the links a of said sails, the sliding bar G', the yokes I, and the pins c and d on said bar, the guides b, and the slotted and weighted lever J, substantially as and for the purpose specified.

8. In combination with the frame D, provided with guides b, and the sliding bar G, the weight-arms J and the rod L, rigidly connecting said weighted arms, whereby the bar G is caused to move exactly the same at both ends, substantially as described.
